Current dikes are made with a core of sand, covered by a thick layer of clay to provide waterproofing and resistance against erosion. Dikes without a foreland have a layer of crushed rock below the waterline to slow wave action. Up to the high waterline the dike is often covered with carefully laid basalt stones or a layer of tarmac. The ...
J. Strom Thurmond Dam, [1] also known in Georgia as Clarks Hill Dam, is a concrete-gravity and embankment dam located 22 miles (35 km) north of Augusta, Georgia on the Savannah River at the border of South Carolina and Georgia, creating Lake Strom Thurmond. U.S. Route 221 (and Georgia State Route 150 on the Georgia side of the state line) cross it.
The dam, which is managed by Blue Earth County, is not unaccustomed to flooding. Repeated inundation over more than half a century had already caused structural damage, according to the county’s ...
